-lho operation of the motor will be underlood to he as follows: Assuming that valve piston 25 is in sueh n. position that groove 21' therein is in alinement with ports 29 and Ill, us shown in F ig. 1 the nir, steam, ete. entering ehumber 22 (trough port 23 will pass through said ulined ports 29 and 31 uml groove 26 into chamber 19* at the upper vnd of'cvlinder 13 and me motor piston 12 will he oreed downwardly. As soon' as the. piston 16 nue-ovens the entrance to pi .39 the nir or steuni will flow through sai pipe 39 to chamber 2T und force vulve iston 25 over so that groove 26* is ulined with ports 30 null 3.3 und the air or Steam will flow therethrough from chamber 22 to pipe 34 und into the lower end of the cylinderforcing. the piston 16 upwardly. At this time :he groove 2li is in alinement. with ports 32 und :t6 und the upper end o cylinder 13 exhausts therethrough' into duct. 35, chamber 27 also exhausting through port 41 into said duet 35. Before the piston 16 reaches the upper extremity of its stroke theentranoe to pipe 40 1s uncovered and. the an' or steam wi l flow therethrough into chamber 28 and force the valve 25 hack to its first described, position', :to uctuate the piston' 16 downwnxjdly.l When the pieton` 16 is being forced downwardly the lower end of cylinder 18 iii .xhnusting through pipe 34, and Orts 37 und 38 und.
